IMPROVEMENT IN RTARY BRUSHES.

Speeiication forming part of Letters Patent No. i, dated October 14, 1873 application filed July 3, 1873.

To all whom it may concern Be it known that I, GEORGE CARLISLE, of Attleborough, in the county of Bristol, State of Massachusetts, have invented an Improved Rotary Brush, of which the following is a speciication This improved rotary brush, as to its bristleholder or body, is made of metal, and otherwise constructed as will be hereinafter described. Y

In the accompanying plate of drawings, Figure l is a side view of my improved rotary brush; Fig. 2, a central cross-section, and Fig. 3 a plan view of a portion of the periphery of the bristle-holder or body.

A in the drawings represents the body or bristle-holder of the rotary brush, which body is made of a wheel form, and of metal; B, the

, riphery of the'wheel-shaped holder A for the bristles, as to its width, extends beyond the outside line of each row of bristle-holes a, and from the periphery toward the center for a spending concentric shoulder, h, upon each side, at and along which the inner end of the f radial bristle-holes a op en-the one row of holes through one shoulder, and the other row of holes through the other shoulder. (See Fig. 2.) l l, wires, one for each row of bristle-bunches. Each bunch of bristles in one row is looped about the wire Zfor such row, and thus, by properly fastening the ends of one wire, the bristle-bunches are secured in the holder A, as Ordinarily in brush-making. At the center of the wheel A is a round hole, D, by which to secure the brush on a center arbor or mandrel, when desired to use it.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is 1 A rotary brush composed of the metallic 'disk A, having the concentric shoulders h h,

and holes or openings a c b b, for receiving the bristles B, said bristles being conned in place by the wire l, substantially as described.

The above speciiication of my invention signed by me this 14th day of June, A. D. 187 3.
